[0056] Technical effects and advantages of the present invention:

[0057] (1) The present invention utilizes a setting mode that cooperates with a column, a cross bar, a rotating rod, a nut seat, a support block, a limit block, a connecting rod, and a matching setting mode.

[0058] (2) The present invention utilizes a setting method in which a connecting rod, a movable rod, a compression spring, a clamping block and a clamping slot are matched. By arranging a cross bar between two uprights, placing one end of the cross bar on the upper surface of the support block, pulling the mounting rod outward to release the limit on the connecting rod, and then pushing the limit block to drive the sliding block to move along the fixed rod, one end of the connecting rod slides in the inner cavity of the movable rod so that its back is in contact with the front of the cross bar, and utilizing the elastic effect of the compression spring to push the extrusion block and the clamping block downward so that the clamping block is inserted in the inner cavity of the clamping slot, thereby ensuring the unidirectional movement of the connecting rod and preventing the limit block from moving toward the front. The limit block stably limits the cross bar;

[0059] (3) The present invention utilizes a configuration in which a cross bar, a connecting groove, a through groove, a support rod and a sleeve are matched with each other. The first bolt is sequentially passed through the inner cavity of the connecting groove corresponding to the column and the cross bar, fixed with a nut, and then the connecting pipe is inserted into the inner cavity of the opposite end of the two cross bars, and the second bolt is inserted into the inner cavity of the connecting groove and the through groove to connect the cross bars, and the support rod and the sleeve are vertically arranged between the cross bars.
